Changing Ember's Settings Via Terminal or Putty


#1

Using a command line utility like SSH or PuTTY allows you to change Ember’s advanced printer settings. The most common setting users change is the Projector LED Current, which controls how bright your projector is. There are two methods of accessing the Ember command line: network IP address or USB cable.

NOTE: if you only need to change your Projector LED Current, you can change it via emberprinter.com if your printer is paired.


METHOD 1: CONNECT VIA NETWORK IP ADDRESS

Windows:

  1. Download and open PuTTY.

  2. Put your printer’s IP in the address field (if you don’t know your printer’s IP address, hold the left button on the printer for 5 seconds to see it), and put 22 in the Port field, then press Enter.

  3. When prompted for a login, type root and press Enter. It may take more than one try. Once you’re successful, you’ll see a root@ember: prompt.

  4. Type nano /var/smith/config/settings and press Enter to open the settings file in a text editor.

  5. Use the arrow keys to scroll down until you find the setting you want to change, then change the number to the right of it.

  6. Hit Ctrl+O, then Enter to save the file. Then Hit Ctrl+X to exit the text editor.

  7. Type echo refresh > /tmp/CommandPipe and press Enter.

  8. Close PuTTY. You’re done!

Mac:

  1. Open a Terminal and type ssh root@[your printer’s IP address], then press Enter. If you get a warning, type yes to continue. If you don’t know your printer’s IP address, hold the left button on your printer for 5 seconds to display the address.

  2. Type nano /var/smith/config/settings and press Enter to open the settings file in a text editor.

  3. Use the arrow keys to scroll down until you find the setting you want to change, then change the number to the right of it.

  4. Hit Ctrl+O, then Enter to save the file. Then Hit Ctrl+X to exit the text editor.

  5. Type echo refresh > /tmp/CommandPipe and press Enter.

  6. Quit Terminal. You’re done!


METHOD 2: CONNECT VIA USB

Windows:

  1. Install the Ember USB drivers if you haven’t already.

  2. Connect your computer to your Ember with a USB cable.

  3. Download and open PuTTY.

  4. Put 192.168.7.2 in the address field, and put 22 in the Port field, then press Enter.

  5. When prompted for a login, type root and press Enter. It may take more than one try. Once you’re successful, you’ll see a root@ember: prompt.

  6. Type nano /var/smith/config/settings and press Enter to open the settings file in a text editor.

  7. Use the arrow keys to scroll down until you find the setting you want to change, then change the number to the right of it.

  8. Hit Ctrl+O, then Enter to save the file. Then Hit Ctrl+X to exit the text editor.

  9. Type echo refresh > /tmp/CommandPipe and press Enter.

  10. If you’re testing your projector LED current using the showwhite command, make sure to turn the projector off and then back on as follows:

    echo showblack > /tmp/CommandPipe
    echo showwhite > /tmp/CommandPipe

  11. When you’re done, you can close PuTTY.

Mac:
